Abstract (en)
[origin: EP0220682A2] A data processing system has a data processing function to perform a data processing by specifying one of a plurality of register groups (BN0, BN1, BN2) according to an instruction. The instruction contains an information for indicating a change from a register group (BN0) to another register group (BN2) and an information for specifying desired one or two or more registers (R2, R15; R7, R12) in said register group(s). This enables to transfer the contents of the desired one or two or more registers to other registers at a register change.
